Super tender; performs well even in clay soil. Very tight head in warm climates, but as temperatures rise above the mid 70's, watch to be sure spears are staying tight. If they start to open, begin cutting at 5" height to ensure tenderness of harvest. Very tolerant of rust and foliar diseases, making Jersey Knight a favorite in humid climates. Medium to large spear size; prolific spear production. Predominantly male hybrid strain, so little or no seed produced. PP6624
